ADJUSTABLE SCENE :PORTAL IN'THEATERS.

Application filed May '26,

T 0 all 'whom t` may concern.'

Be it known that I, MAX HASAIT, subject of' Germany, residing at Dresden, Germany,l

have invented certain 'new and useful mprovements in Adjustable Scene Portals in Theaters, of which the following is a specication.

This invention relates to an adjustable scene-portal in theaters and differs from similar portals heretofore known by the portal surrounding the scene-opening in the form of an adjustable frame, the opening of which can be increased or reduced, the members by means of which the sides of the frame are moved together or apart being invisible from the auditorium and a foot- `bridge being raised and lowered yupon the adjustment of the opening of the portal, while foot-bridges and balustrades are drawn forth from lighting galleries provided inthe sides of the portal, said foot- `bridges being adapted to support different apparatus and scene-Shifters.

Scene-portals have hitherto only been used to increase or reduce the scene-opening and consist generally of thin walls movable sideways and in front of which'draperies are placed which may be raised and lowered thus increasing or decreasing the scene-openim ing. Such an arrangement is connected with the inconvenience that the workman operating the lighting controller cannot look over the scene from his cabin, since in case of a very reduced scene-opening thescenery will hide the view. Another inconvenience connected with such a flat. frame consists in that the foot-bridge is fixedyto the portal and placed so high, ythat in the highest position of the draperies it is concealed to the spectators, and on account thereof a scene passing on in a closed room covered by a ceiling cannot be lighted by means of lighting' apparatus located on the foot-bridge, because of the fixed footbridge being' placed too high fabove the ceiling. Y y

By the aid of a frame constructed at all sides of wide members the advantage is obtained that foot-bridges may be disposed extending, even in case of the smallest portal-opening, immediatelyl to .the scenery, placed near the port-al, it being thus possible to look over and lighten the scene from the foot-bridge. The fireman may be positioned 0n the stage-floor within the side of 1921. Serial No. 472,777.

the frame and is able to look over the scene i to operate the lighting apparatus thereon.

and look over the decreased scene. This applies also to the "stage-manager. l0n footbridges for the, lighting galleriesI located still higher lighting apparatus may bek dis# posed by means of which the rscene may be lighted even in its least size, and besides the.

scene can be lightedbeneath the ceiling' from the upper, lowered footbridge. The controller may for instance be located on one of the foot-bridges and thus be carried on upon the adjustment of the parts of the portal. Said apparatus may by means of conductors, extensible shafts or pipes be connected with the regulating resistance, or otherwise, the latter may be carried on. Owing thereto the yperson managing the controller has always, even in case of the smallest portal-opening, the controller in immediate proximity. Moreover other lighting apparatus and scene-machines may be placed on the movableparts of the portal and connected with devices by `means of which said apparatus are managed. The portal rframe may be of any shape and its parts may be connected by joints of any type. The frame may be coated with stuff, wood, metal or other materials.

In connection with the above-mentioned advantages of great importance in a theater the invention brings about a portal of artistic effect well bounding the scene-opening, without displaying for the spectators the parts by means of which the different members ofthe portal are moved relatively to each other.

An embodiment of the invention is illustrated in the accompanying drawing in which-f j Fig. 1 is a perspective view of the one half of ascenesportal arranged accordingto the invention and viewed from the auditorium.` Fig. 2iis a section on line M c in F ig. kl. 'F 3 is a section on line f-g in Fig. l. Fig. 4 is a section 0n line a-b in Fig. l and Fig. 5 is a section on line cZ-c in Fig. l.

Referring to the drawing, l and 2 are a fore and a rear 'frame-work respectively parallel to each other, and to the middle part oit which a Hoor 3 for instance of wood is rigidly attached and provided at the ends of the frame-works with recesses 9. t designates the lower vside of the upper border of the portal-opening, and above said lower side a slide 5 is attached to the side 1l, 11u of the portal. 14 is a fixed gallery, 13 is a balustrade and 12 is a foot-bridge, the two Vlast-named being connected to the side of the portal and carried along by the same, when moved in the directionV ot arrow 7L in Fig. 1 to the position 16 indicated by stippled lines in Fig. 1. 15 is the door intended for the {ire-man. 17 and 17a designate a box-shaped trame resting on the stage-floor and forming the lower border ot the portalopening. Placed below vthe trame are the lower foot-lights 21, the prompters box and the lighting box. 19 is the stage-floor which supports the scenery 22 above which a ceiling 6 is located. Placed below the latter is a lighting-apparatus '2O capable of lighting the scene. 3 is a transverse stay connecting the frame-works 1 and 2. 7 and 7 designate a coating of metal. stuff, wood or the like connected with the lower side l and directed towards the auditorium. is a wall covering the parts ot the side 1.1` .11a of the portal when drawn out. The wall 23 maybe stationary or movable. 10 designates guides along which the slide 5 is sliding when moved. l

As will appear from Fig. l.. the sceneopening can be reduced Jfrom the positions ot the parts t and 11 shown in said ligure by full lines to the positions ot the same parts indicated by 16 and 1G. The side 11, 1'1n of the portal is preterably` to eliect its movement, supported by rollers 25, Fig. l, and the raising and lowering of the frameworks 1 and Cmay be effected by means oit' hoisting ropes 26 or the like.

That I claim as new and desire to secure by Letters Patent ot the United States 1.
